If you don't know at what point the dishwasher started flashing PF, does this mean that it hasn't gotten through the full cycle and we should start over?

Mine does the same thing. I'm confident that the problem lies in the "computer" which is essentially the buttons for selecting the various wash cycles. That strip is basically a thick band with adhesive on the back by which it is glued to the top of the dishwasher door. There are wires connected to it. The wires run down into the door and connect to a terminal that is built into the door. The inside door panel must be removed to install a new button strip or "computer." Mine was replaced twice in the first year. Now it is three years old and needs to be replaced again. I'm going to look around on the net to see if I can find one.

PF posting had incorrect descripton. I said wrongly that the "computer" was on the top of the door. It's actually on the front of the door at the top. It has the buttons for start/cancel and favorite cycle.

Based off what you are describing "PF" stands for power failure on a Frigidaire dishwasher. If the lights are dimming then your appliance flashes "PF" it could possibly be an issue within your panel or your appliance is not getting enough power to it. I would recommend contacting a professional to come and diagnose your appliance properly. I hope this is helpful. -Matt

I understand that your Frigidaire dishwasher, model# FDB4315LFC2, starts and then stops, and flashes a "PF" code when it stops. The "PF" code is stating that there has been a power failure. There could be a possibility that your dishwasher is losing power mid-cycle. I suggest checking your home's circuit breaker, the wiring to your dishwasher, and if you have a cut-off switch, checking that as well. I also suggest resetting your appliance, by shutting the power off at your home's circuit breaker, for 20-30 minutes. Restore power and start any cycle. If further troubleshooting is needed, I ask that you please let me know the error codes displayed on your appliance. Hope this is helpful.

You will have to reset the dishwasher. First try and turn off the mains power and back on after a short time. If the clean light flashing starts again then you go through the hard reset procedure.

press NORMAL WASH then HEATED DRY buttons one after the other until all the lights on the board lit up (3X's). The dishwasher will enter into a cycle; Press Cancel. This should stop the flashing.If you are supplying dishwasher from hot water inlet then make sure the inlet water temperature stays within the recommended range of 145 deg F.

Hello babe_dog01 - PF typically appears in window when dishwasher is first installed, or when power has been interrupted. HI-TEMP WASH, SANITIZE and START/CANCEL backlighting will also flash. To clear, touch START/CANCEL pad or resetting the unit by unplugging it or flipping the household circuit breaker off. Wait approximately ten minutes. Since you have already done so and it was ineffective contact a professional to move forward accurately. Dishwasher could possibly be experiencing a communication error, wiring failure or faulty control board.

You will have to reset the console. To do this, close the door and press these buttons in sequence...

...all the lights will turn on briefly and the machine will start a diagnostic cycle. You can press cancel or let the diagnostic cyle finish (1-2 minutes). You should now be able to run the dishwasher as normal.
